Reversibly attachable bayonet fitting

Abstract

The invention relates to a bayonet assembly (20) comprising the bayonet fitting (1) and an attachment support (21), wherein the attachment support (21) comprises a domed bayonet recess (24), a bayonet cut-out (25), and more than one dimple (26); wherein the number of more than one dimple (26) of the bayonet assembly is the same as the number of more than one protuberance (7) of the bayonet assembly; wherein in a first orientation the bayonet fitting (1) and the attachment support (21) are detachable from each other, and in a second orientation the bayonet fitting (1) and the attachment support (21) are lockable to each other; and wherein in the second orientation, each of the more than one dimple (26) reversibly accommodates each of the more than one protuberance (7).

1 . A bayonet fitting ( 1 ) comprising a head section ( 2 ), a base section ( 3 ), and a clamping section ( 13 );
 wherein the head section ( 2 ) and the base section ( 3 ) and the clamping section are a single contiguous piece;   wherein the head section ( 2 ) comprises a cylindrical core ( 5 ) that protrudes along the longitudinal axis (A-A) of the bayonet fitting;   wherein the cylindrical core ( 5 ) comprises more than one flange ( 6 ) protruding radially from the circumferential surface ( 12 ) of the cylindrical core ( 5 ) in a direction perpendicular to the longitudinal axis of the bayonet fitting;   wherein each of the more than one flange ( 6 ) comprises the clamping section ( 13 ) and an apex ( 14 );   wherein the base section ( 3 ) comprises an inner facing side ( 8 ) from which the cylindrical core ( 5 ) protrudes, and an outer facing side ( 9 ) that faces the opposite direction to the cylindrical core ( 5 ) along the longitudinal axis of the bayonet fitting (A-A);   wherein the surface profile of the inner facing side ( 8 ) is convex;   wherein the surface profile of the outer facing side ( 9 ) is flat;   wherein the inner facing side ( 8 ) further comprises more than one protuberance ( 7 ) emerging off the inner facing side ( 8 ) in a direction parallel to the longitudinal axis of the bayonet fitting (A-A);   wherein the apex points towards the inner facing side ( 8 ) of the base section; and   wherein the clamping section ( 13 ) comprises the apex ( 14 ), the inner facing side ( 8 ) of the base section ( 3 ) and a protuberance ( 7 ).   
     
     
         2 . The bayonet fitting according to  claim 1 , wherein the bayonet fitting further comprises a tail section ( 4 ) that protrudes from the outer facing side ( 8 ) of the base section ( 3 ) in a direction opposite to the head section along the longitudinal axis of the bayonet fitting (A-A), and the head section ( 2 ), the base section ( 3 ) and the tail section ( 4 ) are a contiguous single piece. 
     
     
         3 . The bayonet fitting according to  claim 2 , wherein the tail section ( 4 ) is selected from an arch or a stud bolt. 
     
     
         4 . A bayonet assembly ( 20 ) comprising the bayonet fitting ( 1 ) according to  claim 1  and an attachment support ( 21 );
 wherein the attachment support ( 21 ) comprises a domed bayonet recess ( 24 ), a bayonet cut-out ( 25 ), and more than one dimple ( 26 ); 
 wherein the number of more than one dimple ( 26 ) of the bayonet assembly is the same as the number of more than one protuberance ( 7 ) of the bayonet assembly; 
 wherein in a first orientation the bayonet fitting ( 1 ) and the attachment support ( 21 ) are detachable from each other, and in a second orientation the bayonet fitting ( 1 ) and the attachment support ( 21 ) are lockable to each other; and 
 wherein in the second orientation, each of the more than one dimple ( 26 ) reversibly accommodates each of the more than one protuberance ( 7 ). 
 
     
     
         5 . The bayonet assembly according to  claim 4 , wherein the bayonet assembly further comprises an internal ( 41 ) comprising an oblong hole. 
     
     
         6 . The bayonet assembly according to  claim 5 , wherein the bayonet assembly further comprises a split-key ( 42 ) or a nut attachable to the tail section. 
     
     
         7 . The use of bayonet fitting according to  claim 1  for the reversible attachment and detachment of internals within reactor vessels, distillation columns and mass transfer units. 
     
     
         8 . The use of bayonet assembly according  claim 4  for the reversible attachment and detachment of internals within reactor vessels, distillation columns and mass transfer units.
